I haven't seen this "strength" issue surface yet with my bearings that everyone says I would, and am smoother than I use to be....but I regularly pull SLAMMING disaster stalls, and that HAS to be a good test of them. Course I have only been riding them about three months.

thats nice to hear about the euroBB. so many riders talk shit about them and have no clue what their talking about. i just got a DK weapon and a Fit series 2. im waiting for my euroBB to arrive.... got both frames brand new off eBay..... i want to see which is more comfy for me. i guess you could say im spoiled but i make good money.

The profile bearings themselves are tough IMO, the thing that sucks is that you dont screw the left side bearing in all the way, you have to run a gap there so the clearences are right. But pedeling and hitting the bb(rare) causes the bearing with the gap to spin in and clap down hard on the spacer in between. This produces a clicking feeling. I hate when my bike doesn't feel smooth. Makes me wonder if I can trust it. I ran the bearings for a while, they never broke or failed to run smoothly even when they were super tight. I dislike them because they need too much maintenance. Lock tite would fix the threading while pedaling though.

The primo bb is of a much better design, only for 22mm though.
The profile comes with two spacers in the middle, depending on bb width.
The primo has one, and the second bearing has a lock ring instead of just having a standard lip. Will work for profile SS, primo, wtp, xs some others I think.

I have the Snafu 4130s and there badass. Holding up very well. If I was to get another pair of cranks they'd either be the Primo Powerbites or the Excels just cause they seem to look really good. Lots of friends here have the Powerbites and they seem to hold up just fine. Good luck with your choice.

rnc rider made and made to his specs and very high quality to give the titanium spindle a lifetime warranty. also the crank arms are 7075 aluminum and are thick very strong and very light. the pedal boss has a titanium insert and a anit-rotation pin so it will never slip, unlike other aluminum cranks but the best part is that this crank is the same price has all others!! cheaper then most profiles, slightly more then snafu(in some places), and equal to most other cranks

im not sure but i just read up on them again and i think the entire crank has a warranty against bending, breaking, and stripping out
